CStor Pool (zpool) commands

Create Pool

To create zpool on a specified disk with cachefile and alias name in io.openebs:poolname and guid as zpool name.

Cachefile helps in importing a pool faster. Guid is used for poolname and alias name, for example testpool, which ensures readability.

zpool create [-o cachefile=/tmp/pool1.cache -O io.openebs:poolname=poolname] <pool1-guid> /dev/sdc1

Delete Pool

Destroys zpool with the same name you provided while creating zpool.

zpool destroy <pool1-guid>

Import Pool

To import zpool with cachefile and poolname,

zpool import [-c /tmp/pool1.cache] <pool1-guid>

To import zpool without cachefile,

zpool import <pool1-guid>

Get Pool

To get poolname without table format -Hp flag is used and to get particular column -o is used.

zpool get -Hp name -o name
zpool get <pool-guid>

Clear pool label

The labels written to disk on previous zpool creation must be cleared.

zpool labelclear -f <disk details>
